John Keats' poem "To Sleep" is written in traditional English lyrical form which consists of six stanzas with six lines each. It contains an ABAB rhyme scheme and a Trochaic tetrameter rhythm. Additionally, the poem employs several use of figurative language including personification, metaphor and simile. An example of a metaphor is in the line “Come, blessed barrier between day and day,” where Keats metaphorically calls sleep a barrier between two days.
